Transcript

Question 9 You are given two sets of number cards numbered from 1 – 9. Place a number card in each box below to get the (a) largest possible sum The problem gives you some special number cards. You have two of each number from 1 to 9. So, you have: Two '1's Two '2's Two '3's Two '4's Two '5's Two '6's Two '7's Two '8's Two '9’s You need to put these cards into boxes to make two numbers. The top row has 7 boxes, so you'll make a 7-digit number. The bottom row has 5 boxes, so you'll make a 5-digit number. The goal is to make the biggest possible SUM when you add these two numbers together. So, we need maximum 7-digit and maximum 5-digit numbers from these Thus, two numbers to get maximum sum is 9987654 & 87654 Question 9 You are given two sets of number cards numbered from 1 – 9. Place a number card in each box below to get the (b) smallest possible difference of the two resulting numbers.The goal is to make the smallest possible Difference when you subtract these two numbers together. So, we need minimum 7-digit and maximum 5-digit numbers from these Thus, two numbers to get maximum sum is 1122334 & 99887
